Raised serum levels of adhesion molecules are believed to reflect endothelial activation and may contribute to the development of diabetic vascular complications. The aim of this study was to clarify the association between soluble adhesion molecules levels and retinopathy in type 2 diabetic patients. Levels of soluble E-selectin, ICAM-1 and VCAM-1 were measured by enzyme-linked immunosorbent assay (ELISA) in 47 type 2 diabetic patients classified in two subgroups according to the presence (n=34) or absence (n=13) of retinopathy as determined by fundus ophthalmoscopy; 22 control subjects were also studied. Soluble E-selectin levels were significantly elevated in both diabetic subgroups compared to control subjects (p<0.01), while no significant difference was found in sICAM-1 and sVCAM-1 levels. However, sE-selectin, sICAM-1 and sVCAM-1 levels were comparable in diabetic subgroups. The progression of retinopathy was not associated with an increase in soluble adhesion molecules levels. Stepwise multiple regression analysis revealed that only diabetes duration and microalbuminuria were independent determinants of retinopathy (p<0.01). Our results confirm the contribution of endothelial activation in the development of diabetic complications as indicated by increased levels of soluble adhesion molecules. However, a direct implication of adhesion molecules in the pathogenesis or progression of type 2 diabetic retinopathy cannot be supported.

Early-onset type 2 diabetes (T2DM) may lead to very early vascular complications. Cardiovascular mortality is two to five times higher in adults with diabetes than in people without diabetes. The cardiovascular risk of young people with T2DM is unknown. T2DM in young people is associated with marked visceral obesity, insulin resistance and microalbuminuria. We recently showed that these subjects did not improve in either fitness (maximum volume of oxygen consumption, VO2max) or glucose disposal after exercise training. Seven subjects with early-onset T2DM (aged 26.1+/-0.9 years, body mass index [BMI] 35.6+/-1.2 kg/m2) and 14 age-matched obese subjects with normal glucose tolerance (aged 25.6+/-0.9 years, BMI 34.3+/-1.4 kg/m2) underwent aerobic training for 12 weeks. Serum vascular inflammatory markers (high-sensitivity C-reactive protein [hsCRP], soluble intercellular adhesion molecule [sICAM-1], soluble vascular cell adhesion molecule [sVCAM-1], E-Selectin and P-Selectin) were measured before and after the training programme. At baseline, plasma concentrations of vascular inflammatory markers were significantly elevated in both groups. They did not improve after exercise.

Objective Endothelial dysfunction (ED) plays an important role in the pathogenesis of diabetic nephropathy. The purpose of the study was to determine flow mediated endothelial dependent vasodilatation (FMD) measurements and serum soluble (s) endothelin-1 (ET-1), intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule (VCAM-1) levels in patients with type 1 diabetes mellitus (T1DM) with or without increased urinary albumin excretion (UAE) and compare them with the healthy controls. Subjects and methods Seventy three patients with T1DM were enrolled. Patients were divided into two subgroups according to microalbumin measurements in 24-hr urine collections. The diabetic patients without microalbuminuria (41 patients) were defined as Group I and those with microalbuminuria (32 patients) were defined as group II. A hundred age and sex matched healthy subjects participated as the control group (Group III). Serum sET-1, sICAM-1, sVCAM-1 levels and FMD measurements were determined in all participants. Results Median FMD measurement was significantly lower in the diabetic groups compared with the control group (6.6, 6.4 and 7.8% in Group I, II and III, respectively) (p < 0.05). FMD was negatively correlated with age (p = 0.042). Median serum sICAM-1 level was higher in the patient groups compared to the control group (p < 0.05). Median serum sVCAM-1 level was higher in the group of patients with increased albuminuria compared to the normoalbuinuric and the control group (p < 0.05). Serum sVCAM-1 level was found to be positively correlated with degree of urinary albumin excretion (p < 0.001). Conclusion We assume that sVCAM-1 may be used as a predictive marker for risk stratification for nephropathy development and progression.
